PREVENTION OF ADHESION OF BACTERIA, MICROORGANISM, BARNACLE, PEARL SHELL, UNDARIA, ETC. TO FISHING NET, FISHING GEAR, BOTTOM, BATHROOM AND BATHHOUSE AND ADHESION PREVENTING METHOD FOR THE PREVENTION
PROBLEM TO BE SOLVED: To provide a method of preventing adhesion of barnacle, etc. to a crawl net or a bottom and a method of removing snow coverage on a roof.SOLUTION: A method of preventing adhesion of e.g. barnacle comprises kneading a polyethylene resin with e.g. calcium hypochlorite and processing the polyethylene resin into a fibrous form to make a crawl net for cultivation of e.g. yellow-tail. Adhesion of marine organisms to the bottom is prevented by mixing e.g. a urethane coating with a metal or carbon to impart electric conductivity, applying the coating to e.g. the bottom of an FRP ship and electrifying an electric current to electrolyze sea water to form e.g. calcium hypochlorite on the surface of the bottom. The surface of a pavement can be illuminated by applying the conductive coating to the surface of the pavement 39 as a line coating for roads, like 46 and 47 in the illustration, and electrifying a current to e.g. a sealed LED lighting fixture 43 to light. Snow coverage on a roof can be molten by using a roof material including the conductive resin and electrifying a current.【課題】生け簀網、船底にフジツボ等の付着を防止する方法、屋根の積雪を取り除く方法等を提供する。【解決手段】次亜塩素酸カルシウム等をポリエチレン樹脂に練り込み、これを繊維状としてハマチ等を養殖する生け簀網を作り、フジツボ等の付着を防止する方法。金属やカーボンをウレタン塗料等に混合して導電性を持たせ、ＦＲＰ船等の船底に塗布し、電流を流して海水を電気分解し、船底表面に次亜塩素酸カルシウム等を発生させて、海棲生物の船底への付着を防止する。さらにこの導電性塗料を道路用のライン塗料として舗道３９の表面に４６，４７のように塗布し、電流を流して密閉したＬＥＤ等照明器具４３を点灯させて舗道表面を照らすことが出来る。また、導電性樹脂を用いた屋根材を使い、電流を流して屋根の積雪を溶かすことが出来る。【選択図】図５７
